SHIFTING DEVICE AND STOP MECHANISM FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed September 18, 1916. Serial No. 120,836.

To all whom it may concern.-

Be it known that I, LUTHER S. HOPKINS, a citizen of the United States, and a resident of the city of Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improve ments in, Shifting Devices and Stop Mechanisms for Talking-Machines; and I do hercby declare that the following is a' full, clear, and exact description of the same, reference being bad to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a shifting mechanism forming a part of the driving means of a talking machine, whereby a record may be re-played any number of times desired upon the machine, the mechanism operating automatically for the pur pose, and with a stop device associated therewith, which, when set for operation, serves to bring the driving means of the machine to rest at the completion of the playing of a record.

In illustrating and describing my invention, I have shown a form of device designed for use in conjunction with the Edison type of talking machine, but of course, it is to be understood that with slight variation, the same may be adapted for use on any talking machine.

It is an object therefore of this invention to construct a mechanism for driving the record carrying means of a talking machine, operating automatically to shift the reproducer or sounding arm back to initial playing position at the completion of the playing of a record to again play the record and continue so for as long as desired.

It is also an object of this invention to construct a talking machine mechanism wherein by adjustment of a suitable lever provided for the purpose, a record of any size may be caused to be played continuously by the machine, the mechanism operating automatically to shift the reproducer arm back to initial playing position on the record at the completion of playing thereof, the successive shifting movements taking place as long as desired, so that the same record may be played over and over for any length of time.

It is also an important object of this invention to construct a mechanism operating to drive the record carrying means of a talking machine continuously and serving to shift the reproducer back to initial playing position at the completion of the playing of the record so that the record may be played any number of times, and furthermore provided with an automatic means serving to disconnect-the drive from the record carrying means at the completion of the playing of the record ifso desired.

It is also an object of this invention to construct a driving means for the carrying mechanism of a talking machine whereby the machine may be set to operate automatically to replay the record any number of times, and said mechanism may also be caused to cease operation at the completion of the playing of a record if so desired, to gether with devices for controlling the speed of operation of said mechanism.

It is furthermore an important object of this invention to construct a driving and governing mechanism for talking machines whereby a record may be replayed on the machine successively any number of times desired, and whereby by properly setting the mechanism, the same may be caused to cease operation at the completion of the playing the record, said mechanism being adjustable for records of different size, and provided with means to govern the rate of drive of the machine.

It is finally an object of this invention to construct a driving mechanism for talking machines whereby a record may be replayed any number of times desired, and by prop erly adjusting said mechanism, may be caused to cease operation at the completion of the playing of a record on the machine.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown on the drawings The reference numeral 1, indicates the cabinet or casing of the talking machine which is provided with a horizontal partition 2, having the major portion thereof cut away to receive a frame plate 3, recessed theneinto flush therewith to be sup rted thereby. Attached to the under sur ace of the frame plate 3, as shown in Figs. 3 and 4, is an electric motor 4, which serves section taken on line to drive a shaft 5, journaled in cone or center bearing brackets 6, depending from each side of said frame plate 3. Said motor 4, serves to drive the shaft 5, through a friction coupling consisting of an outer shell 7, which is secured to the motor shaft, and an inner disk 8, secured to the shaft 5, with re silient friction members 9, secured on the inner surface of the outer shell 7, bearing upon the periphery of said disk 8, with the bearing pressure made variable by the use of set screws 10. Mounted on the outer end of the shaft 5, is a centrifugal ball governor denoted as a whole by the reference numeral 11, and a friction disk 12, forms a part of said governor mechanism which is drawn inwardly against brake shoes 13, mounted on the yoked end of a long pivoted lever 14, when the governor balls fly outwardly.

As clearly shown in Fig. 3, the outer end of said lever 14, is connected to a tension spring 15, which is secured to the under surface of the frame plate 3, and said lever is further provided with a slot 16,

slidably engaged on a stud 17, secured into the under surface of the frame plate to thereby limit the swinging movement of said lever 14, which serves to vary the friction effect upon the governor friction disk 12. The end of said lever 14, is also provided with a notch into which the tooth of a cam 18, engages which is mounted on a vertical spindle which is journaled upwardly through the frame plate 3, and which on its upper end on the top side of said frame plate 3, is provided with an adjusting head 19.

J ournaled vertically and centrally through the frame plate 3, is a shaft 20, shown in Fig. 11, the lower end of which is seated in an end or ball thrust bearing 21, which is mounted in a bracket extension 22, extend' downwardly from beneath and integr h? with the frame plate 3. Secured upon the upper end of said shaft 20, above the frame plate 3, as clearly shown in Fig. 2, is a record carrying disk 22, upon which a record to be layed is placed. Journaled upon said sha t 20, is a worm wheel 23, which is at all times g ed with a worm 24, formed on said shaft 5. An extension arm 25, is provided upon the bracket 22, extending outwardly therefrom in which a center bearing member 26, is mounted affording a support for one end of a shaft 27, the other end of which is supported upon the center bearing member 28, mounted in a bracket extension 29, depending from the other side of the frame plate. Secured upon said shaft 27, is a worm ear 30, which is in mesh with a worm 31, ormed or secured upon the shaft 20, so that said shaft 27, is driven at all times. Secured upon the other end of said shaft 27, is a worm 32, and this worm serves to drive a worm gear segment 33, shown in Figs. 9 and 14, which is pivotally mounted upon a pintle 34, of a bracket extension 35, which is mounted upon the recorder arm structure hereinafter described, so that said structure is caused to Y swing owing to the movement of the worm gear segment driven by said worm 32. Said gear segment member 33, is rovided with a ownwardly bent aperture tail extension 36, engaging slidably upon a stud 37, secured in said bracket extension 35, with a coil spring 38, dis osed around said stud and bearing upwar y beneath said tail extension to tilt the gear segment about its pintle 34, and maintain the segment in mesh with the worm 32.

Journaled vertically beneath the frame plate 3, with its lower end supported upon a bearing bracket 39, is an upright shaft or rod 40, on which is slidably mounted a sleeve 41, which in turn has secured thereon said bracket extension 35, said sleeve 41, affording a support for the end of a soundinghnrnfl, whichispmveided atubu-- lar arm extension 43, extending upwardly through the frame plate 3, to receive a recorder or needle carrying arm (not shown) of usual construction attached thereon A slot is provided in the partition wall 2, to permit swinging movement of the upwardly extending arm 43, of the horn. Formed upon the upper end of the vertically movable shaft 40, is a horizontally slotted cylindrical head 44, disposed directly above the bracket extension 35, and provided on its interior with a roller 45, as clearly shown in Figs. 7 and 9. Slidably mounted through said head 44, beneath the roller 45, is a tapered or inclined end 46, of a slide bar 47, which at its opposite end is slotted, and as clearly shown in Fig. 7, is slidably engaged on each side of a stud or pintle 48, secured on a downwardly directed extension of the frame plate 3. The slide bar 47, has a roller 47, rotatably mounted thereon. The end of the slide bar extends through a slotted supporting head 49, therefor, provided with a roller 50, upon which the under surface of said bar rides during sliding movement of the bar. Journaled upon a stud which is threaded into said stud 48, is a relatively large gear wheel 51, and secured above said gear wheel 51, to rotate therewith, is a cam 52, as clearly shown in Fig. 3. Said slidable bar 47, is normally held retracted by a tension spring 53, connected to the slotted end thereof, and to a stud 54, secured in the under surface of the frame plate 3, as shown in Fig. 7. At one point in its periphery, as shown in Figs. 5, 7 and 8, three of the teeth of the gear 51, are cut away, and in place thereof, a slidablc tooth 55, is provided which extends inwardly into a recess in one of the spokes of the gear, being provided with a tail extension 56, which projects upwardly from the gear and also affords a stop for a coil spring 57, which acts normally to hold said tooth 55. retracted. The mutilated gear 51, is disposed to mesh with a pinion 58, which is journaled on a downwardly extending stud 59, secured beneath the frame plate 3. Also journaled upon said stud 59, and connected to rotate the pinion 58, is a larger pinion 60, which meshes with and is driven by a pinion 61, secured upon the vertical shaft 20.

The retracted tooth 55, of the gear 51, may

- be thrust outwardly to engage the gear 51.,

with its driving pinion 58, and for this purpose, ivotally mounted upon. a stud shaft 62, beneath the frame plate 3, is a bell crank 63. one crank extension. of which is adapted to strike the stop member 56, to impel the same and the tooth outwardly againstthe stress of the spring 57. The other arm of said bell crank has connected thereto a tension spring 64, which normally maintains said bell crank in the retracted position such as shown in Fig. 5. A long rod 65, is provided which is slidably mounted through the end of one of the arms of said bell crank 63, as clearly shown in Fig. 5, and said rod 65, is provided with stops 66 and 67,

thereon. The end of said rod 65, is pivotally connected to a release mechanism comprising an arm 68, of a T-shaped bell crank, having a second arm 69, and also an arm 70, said crank being pivoted upon a stud 71, secured in a disk 72, which is adjustably and eccentrically pivoted on the under surface of-the frame plate 3, on a pintle 73, said pintle also serving as a stop to limit the movement of the T-shaped bell crank. A tension spring 74, is connected to the arm 70, of said bell crank, and to a fixed point on the under surface of said disk 72, acting normally to hold said T-sha-ped bell crank either on one side or the other of dead center position of the arm 70, thereof. The pintle 73, extends upwardly through said frame plate 3, and on its upper end is provided with a crank arm 75, as clearly shown in Fig. 1, movable into different positions through a small arc beneath a curved guide bar 76, on the top surface of said frame plate 3. to permit adjustment of said disk 72, into different positions about its eccentric pivot 73 to set the release mechanism to permit records of different sizes to be played. Another stop 77, is also provided upon said eccentrically mounted disk 7 2, to limit the movement of the T-shaped bell crank by contact with the arm 68, thereof, as shown in the possible dotted line position thereof illustrated in Fig. 5. The normal position of the release mechanism just described during the playing of a record is that shown in Fig. 5.

For the purpose of actuating the release mechanism to cause the record playing mechanism to be shifted to the initial point on the record after the record has been played, to re-play the record, a mechanism is provided consisting of an upwardly projecting pin 78, secured in the gear segment lever 33, as shown in Figs. 5 and 9, which is disposed to contact the crank arm 70, to swing the same beyond dead center position whereby the spring 74, completes the movement thereof, thereby swinging the crank arm 68, into the extreme dotted line position shown in Fig. 5, thus retracting the pull rod 65. lVhen this takes place, the stop 67, on said rod. strikes the bell crank 63, swinging the same into the dotted line position shown in Fig. 5, to impel the tooth 55, into mesh wit-h the constantly driven pinion 58, thereby causing the gear 51, to be rotated, and entrainedjwith' the pinion 58, to be driven a complete revolution thereby. Of course, the moment the tooth 55, moves out of engagement with the pinion 58, it is retracted by its spring, and upon the completion of the revolution of a car 51, the tail extension 55, on said toot strikes against a stop pin 79", depending from the under surface of the frame plate 3, to positively limit the rotation of said gear 51, to one revolution.

The mechanism on the disk 72, operates automatically to return the small bell crank 63, to initial position before the completion of the revolution of the gear 51, so that the tooth 55, will not be a ain struck outwardly. For this purpose, t e pin 78, of the r segment bar 33, upon its return toward initial position, as the sounding horn and recorder arm are moved toward initial position, causes retraction of the T-shaped crank by contact with the arm 69, of the crank, thereby retracting the same until the lever 70, of said crank moves beyond dead center position, whereupon the spring 74, completes the movement thereof, thereby thrusting the rod 65, outwardly so that the stop 67, thereon, releases the crank 63, for movement under the stress of its spring 64, into neutral position.

An electric automatically operatingswitch mechanimn is provided, which may be set so that the current to the electric motor 4, is cut 05 at the completion of the first playing of a record, if so desired. For this purpose, a long lever 79, is pivoted on the under surface of the frame plate 3, as shown in Fig. 5, and mounted thereon is an insulating block 80, provided with one switch terminal contact member 81, and another switch terminal contact 82, with a knife switch closure 83, pivoted adjacent thereto and in direct communication therewith, and with an actuating handle 84, for throwing said lmife blade switch closure element into open position a inst the stress of a tension spring 85. Said ong lever 79, may be swung into a position about its pivot whereby the handle 84, of the switch mechanism is disposed in the path of movement of the stop 66, on the rod 65, so that when the release mechanism is moved into 0 rating position, at the completion of the p aying of a record, the switch element closure 83, will be swung into open position, thereby cutting of the current from the motor 4, and the entire talking machine mechanism then comes to rest. An actuating handle 86, is provided on the end of the long lever 79, projecting upwardly around the edge of the frame plate 8, at a convenient point to be set by the operator of the machine.

A manually o arable mechanism is provided for elevat ng the sounding horn and reproducing arm thereof, so that the needle carrying arm, (not shown) ma be elevated out ofcontact with a record i it is so desired to leave the machine in such position. For this purpose, a pair of integral sector shaped cams 87, provided with an upstandon the upper surface of the frame plate 3, and are provided with slots 89, engaging a pin 90, which is secured in the vertically slidable shaft 40, so that when said handle 88, is pulled downwardly into the dotted line position shown in Fig. 16, the slots will cause elevation of said pin and with it the shaft 40, to hold the same and the sounding horn and recording arm as well as the needle carrying arm (not shown) of the mechanism in elevated position, so that a record cannot be played thereby.

The operation is as follows:

When it is desired to play a record upon the machine, the handle 86, is swung to one side whereby the lever 79, and the switch block 80, are moved into the position shown in Fig. 5, so that the handle 84, is thrown to closed position by the spring 85, current to the motor 4, is supplied and the driving mechanisms of the machine are set in operation. The needle carrying reproducing arm (not shown) is then lowered upon a record which is placed upon the usual carrying disk or table 22', shown in Fig. 2, with the handle 88, of the elevating 'cams 87, of course, swung into upright osition, such as shown in Figs. 2 and 16. is the record is played, the reproducing arm 43, is moved along by the small worm 32, meshing with the worm gear segment 33, which is tiltablv mounted and spring impelled so as to be held in engagement therewith, and is attached upon the bracket 35, whereby the movement imparted to said gear segment by the worm 32, is transmitted to the born 42, and reproducer arm 43, causing the same to swing about the pivot shaft 40, the reproducer arm 43, moving in the slot in the partition 2. The reproducer arm 43, travels inwardly with the needle carrying means (not shown) positively driven by the worm gear segment described, and the slotted head 44, attached upon the pivot shaft 40. of course, swings likewise, but without interference with the tapered end 46, of the slide bar. owing to the shape of the slot as shown in Fig. 3, which permits a certain range of pivotal movement thereof.

However, after the needle has moved to the extreme position on the record, the arm or gear segment bar 33, will have moved into a position such that the upstanding pin 78, thereon, strikes against the arm 70, thereby swinging the same beyond dead center position, and the movement thereof is completed by the tension spring 74, which swings the T-shaped crank in a clockwise direction, referring to Fig. 6. thereby retracting the rod 65, shown in Fig. 5. pulling the stop 67 thereon against the bell crank 63. which slides the slidable gear tooth 55, outwardly against the stress of its spring, into mesh with the continuously driven pinion 58, thereby starting the gear 51, inmovement so that the same makes one complete revolution driven by the pinion 58. This movement of the gear 51, causes a similar movement of the cam 52, attached thereto and the movement of the cam 52, causes the roller 47, which is secured upon the slide bar 47, to travel outwardly on the periphery of the cam, thereby moving the slide bar rearwardly and likewise sliding the tapered head 46, of said bar inwardly beneath the roller 45, as shown in Fig. 7, of the head 44, thereby elevating the pivot shaft 40, and with it the horn 42, and reproducer arm 43, whereby the needle arm is elevated from the record which has been played. This elevating movement also serves to elevate the worm gear segment 33, from engagement with its worm 32, and the reproducer arm 43, is then swung around its pivot to re-play the record. This return swinging movement of the parts to initial position is accomplished by the movement of the cam driven slide bar 47, which is provided with an extension 91, which strikes against a pin 92, projecting on one side of the slotted head 44, thereby rotating said head and with it the associated mechanisms, and shortly after return of the mechanisms to initial position, the slide bar 47, is retracted by the spring 53, as the roller 47, is drawn back to normal position along the straight edge of the cam 52, as said cam 52, completes its revolution, so that the head 46, slides outwardly from beneath the roller 45, thereby gradually lowering the reproducer 43 and horn, and needle carrier means so that the needle is gradually lowered into playing position on the record. The playing needle is prevented from striking the record with force, due to the fact that in the retraction of the head 46, the roller 45, gradually rollsdownwardly on the inclined edge of said head. This return of the reproducing mechanism, of course, operates a return therewith of the gear segment member 33, and the pin 78, thereon strikes against the arm 69, of the T-shapcd bell crank, thereby retracting the same into its initial position against the stop 73, so that the rod 65, is impelled outwardly and the bell crank 63, is thereby released from the stop 67, and swings into initial position under the impulse of its spring 64. At the end of the complete revolution of the gear 51, the same is brought positively to rest by the stationary stop pin 79 striking against the tail portion 55*, of the slidable tooth which is, of course, in its retracted position.

If it is desired, after the completion of the playing of a record upon the machine, the mechanism may be brought to rest automatically. For this purpose, the long lever 79, is swung into the dotted line position shown in Fig. 5, by its handle 86,shown 1n Fig. 1, and as a result, on the completion of the playing of a record, when the rod 65, is drawn inwardly in the manner previously described, the stop 66, thereon, will strike against the handle 84, opening the switch closure blade 83, so that the current to the motor 4, is cut off, and all the mechanisms will come to rest. The electric circuit to the motor will remain disconnected and the mechanisms will remain at rest until the lever 79, is manually returned into its full line position shown in Fig. 5.

An adjustment for speed is obtained by adjustment of the bent lever 14, whereby the pressure of the brake shoes 13, upon the brake disk 12, may be changed. This swin inc movement of the bent lever 14, is o tained by adjustment of the head 19, shown in Fig. 1, which serves to rotate the cam 18, shown in Fig. 3, thereby swinging said bent lever against the tension of its spring 15, for the purpose. Fluctuations in the driving speed of the motor 4, have no eiiect upon the constancy of operation of the driving mechanisms owing to the friction coupling connection between the motor and said mechanisms shown in detail in Fig. 13, so that a tone of uniform pitch is always obtained when the record is played.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
